Psychological implications of vitreous opacities – A systematic review

Given that depression and anxiety can be comorbid to several treatable eye diseases, it is paramount to understand whether vitreous opacities are also associated with increased risk of well-being and mental health problems. The current systematic review summarises research examining psychological implications of vitreous opacities in adult patients.PubMed, Cochrane library, EMBASE, Global Health, Web of Science, EBSCO, and Science Direct were systematically searched for all articles published up to May 5th 2021. Inclusion criteria included studies that have assessed outcomes related to patients' mental health; well-being; quality of life; coping with the disease; studies exploring patients' experiences/perceptions/cognitions of illness and/or medical treatments related to vitreous opacities.5 studies were included in this review, with a total of 139 patients [278 eyes] assessed. Patients' age ranged from 32 to 78 years old. Compared with healthy controls, patients with vitreous opacities showed significantly higher levels of symptoms of depression, perceived stress, state anxiety, and trait anxiety. Studies also suggested that patients are more likely to show low vision-related quality of life, and social functioning. Studies also suggested a significant positive effect of medical treatments [e.g. pars plana victretomy] on patients' symptoms of depression and anxiety and on patients' vision-related quality of life.The topic of psychological implications of vitreous opacities is still relatively new in the literature with very preliminary evidence of mental health problems and reduced quality of life associated with this condition.
